Show HN: Blueprint: Fast, Nunjucks-like templating engine for Java 8 and beyond
I love the simplicity, expressibility and extendibility of Nunjucks.
But I was not able to find something with similar for Java, especially with the same syntax.
So, built one. And it's pretty fast too.

- susika 1y agoLooks interesting. For me I settled on JTE as the go-to template engine for Java. For anyone curious: https://jte.gg https://jte.gg @freakynit - have you seen this one before? how's it compares with Blueprint?
- freakynit 1y agoPowerful. But I absolutely adore nunjucks syntax and how easy it is to extend it. Hence, I built Blueprint to give me that same feel in Java. I have used this btw, professionally :)
- sshine 1y agoGood to know. Normally I'd use Spring Boot and get the batteries-included experience if I ever were to make web with Java. But I could totally imagine needing a pure, well-made, zero-deps template engine for custom jobs. I certainly have similar libraries in my bookmarks for other languages, like Haskell [1] and Rust [2]. [1]: https://hackage.haskell.org/package/heterocephalus [2]: https://crates.io/crates/minijinja
- deanebarker 1y agoSyntax looks very much like Liquid. I feel like that syntax is becoming a standard.
- whalesalad 1y agoafaik django or jinja invented this syntax? then we saw handlebars, which is where liquid got its influence.
- ekspreso 1y agoIsn't Pebble Templates similar to this? https://pebbletemplates.io/ https://pebbletemplates.io/
- freakynit 1y agoAhh... this is very very similar. I don't know why it didn't show up in Google search. Thanks for mentioning this.
- nashashmi 1y agoWe never hear about Java on this forum. That makes a post like this peculiarly interesting
- TeaVMFan 1y agoIf you're interested in Java template engines for the client side (SPAs), you can look at Flavour: https://flavour.sourceforge.io/ https://flavour.sourceforge.io/ While templates are a big part of Flavour, it also includes routing, components, and idiomatic invocation of Java services. The book on Flavour is here: https://frequal.com/Flavour/book.html https://frequal.com/Flavour/book.html Example 5-letter word game single-page app made with 100% Java, 100% Flavour: https://frequal.com/wordii/ https://frequal.com/wordii/
- splix 1y agoAlso, for SPA with SSR take a look at Double View https://github.com/emeraldpay/double-view https://github.com/emeraldpay/double-view It's a React renderer that works on Java backend by using GraalVM, and then the same JS template continues to work in browser.
- redditor98654 1y agoInteresting. I have used free marker. Pretty happy with it in general. But inability to mutate collections is an annoyance. I will checkout blueprint. A zero dependency library is always a bonus. I don’t see any mention of thread safety in the docs for the engine though.
- freakynit 1y agoHey, Blueprint rendering was already thread-safe. Only the function/filter registrations, IF done during rendering phase, was not thread-safe. I have just pushed small update to make even these thread-safe now. Entire library is now fully thread-safe. Updated README as well. Thanks for pointing this out.
